map(func, iterable)) return results # 示例使用 if __name__ == '__main__': def square(n): return n ** 2 numbers = range(10) results = thread_safe_map(square, numbers, max_workers=4) print(results) 在这个例子中,我们假设 square 函数是线程安全的,因为它不访问任何共享状态。如果 ...
使用ThreadPoolExecutor,可以将函数和可迭代对象结合起来进行线程安全的操作。 fromconcurrent.futuresimportThreadPoolExecutordefsquare(x):returnx*x numbers=[1,2,3,4,5]withThreadPoolExecutor(max_workers=3)asexecutor:results=executor.map(square,numbers)squared_list=list(results)print(squared_list)# 输出: ...
thread1=threading.Thread(target=print_numbers)thread2=threading.Thread(target=print_letters)# 启动线程 thread1.start()thread2.start()# 等待线程完成 thread1.join()thread2.join()print('主线程结束') 在这个示例中,我们定义了两个函数print_numbers和print_letters,分别用于打印数字和字母。然后创建了两个...
安全专家已经确定 Python 是一种用于开发信息安全工具包的语言,例如 w3af。模块化设计、易读的代码和完全开发的库套件使 Python 适合安全研究人员和专家编写脚本并构建安全测试工具。 基于Python 的工具包括各种类型的模糊测试工具、代理甚至偶尔的漏洞利用。Python 是当前几种开源渗透测试工具的主要语言,从用于内存分析的 ...
executor.map(worker, range(5)) 1. 2. 3. 4. 5. 6. 7. 这里使用ThreadPoolExecutor创建了一个最多包含5个线程的池,并通过map方法并发执行了任务。 线程同步 在多线程环境下,线程同步是保证数据一致性和线程安全的重要手段。🔒Python的threading模块提供了多种同步原语,如锁(Lock)、条件变量(Condition)等...
The mechanism used by the CPython interpreter to assure that only one thread executes Python bytecode at a time. This simplifies the CPython implementation by making the object model (including critical built-in types such as dict) implicitly safe against concurrent access. Locking the entire inte...
parsePath的thread方法,是开启多线程,调用auto_config方法中的netmiko自动下发配置。 class autoConfig: --snip-- def thread(self, dev_info_list, dev_config_list): end = list() start_time = time.time() with ThreadPoolExecutor() as executor: results = executor.map( self.auto_config, dev_info...
